“Since Mind knows no divisions into separate entities, phenomena must be equally undifferentiated. Since Mind is above all activities, so must it be with phenomena. Every phenomenon that exists is a creation of thought; therefore I need but empty my mind to discover that all of them are void.

It is the same with all sense-objects, to whichever of the myriads of categories they belong. The entire void stretching out in all directions is of one substance with Mind; and, since Mind is fundamentally undifferentiated, so must it be with everything else.

Different entities appear to you only because your perceptions differ — just as the colours of the precious delicacies eaten by the Devas are said to differ in accordance with the individual merits of the Devas eating them!”
